What drives cost
Removal, wet-layer replacement, attachment method, insulation and complicated equipment details can change the project substantially. Residential shingle rates do not apply.

TPO is a thermoplastic single-ply membrane whose sheets are heat-welded together. Repair and replacement planning needs attention to the welds, substrate and flashing at every roof opening.
Free roof inspections. Repairs, replacements and commercial roof help.
A seam opening and a field puncture require different preparation. The existing membrane’s condition and compatibility determine whether the new material can form a dependable weld. Dirt, deterioration and concealed moisture need to be assessed before a patch is treated as the answer.
At equipment curbs, corners and pipes, the membrane turns out of the horizontal roof plane. Those transitions need secure, compatible flashing and room for the building and material to move.


Attachment, insulation and the deck establish what can remain and what must be removed. Wet insulation cannot be made dry by covering it.
The insulation arrangement, slopes and outlets need to work with the roof’s layout. Drain connections and perimeter details belong in the system scope.
Sheet layout, welding, fastening and flashing need to follow the selected system. Walk routes to equipment help protect the finished surface from service traffic.
Removal, wet-layer replacement, attachment method, insulation and complicated equipment details can change the project substantially. Residential shingle rates do not apply.
Keeping drains open and checking seams, edges and service-traffic damage helps identify defects before they expand. Maintenance does not reset the membrane’s condition or remove hidden moisture.
